BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 623,826, dated April 25, 1899. Application filed August 18,1898. Serial No. 688,919. (NomodeL) To all whont it may concern:

Be it known that we, SAMUEL RANKIN and CHARLES E. STORM, citizens of the United States, residing at Strasburg, in the county of Shelby and State of Illinois, have invented certain new and useful Improvements in Baling-Presses; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in baling presses or machines of that class embodying mechanism for automatically compressing hay, straw, and materials of like character into the form of bales and forapplying binding cords or wires around the material while in a state of compression.

The objects of the invention are, first, to provide a machine of this character having improved mechanism whereby the several successive operations of feeding, compress ing, binding, and delivering the material in the form of bales may be rapidly, conveniently, and effectually performed and choking of the material in the hopper and irregularities in the feed prevented; second, to provide simple and effective packing devices for 1 receiving the material from the feeding-fork and forcing the same into the baling-chamher; third, to provide an improved form of needle and coacting devices for threading the binding cords or wires with certainty at the tomatic clamping means for holding the free ends of the binding cords or wires while they are being twisted and tied; fifth, to provide an improved and efficient construction of mechanism for twisting and cutting the hinding-wires; sixth, to provide simple and positive mechanism for imparting motion to the various operative parts of the apparatus and intermittent mechanism for throwing the wire-threading needles and twisting and cutting mechanism into and out of operation,and,

finally, to generally simplify and improve the construction and render more efficient and certain the operation of this class of apparatus generally.

To these ends the invention consists in the features and in the construction, combination, and arrangement of parts hereinafter :tion of the machine.

Fig. 21 is a diagrammatic perspective view showing the manner in which the binding-wires are held by the clamping-irons U7 and while being twisted and cut.

Referring now more particularly to the drawings, wherein like numerals of reference designate corresponding parts throughout the several views, 1 represents the main frame of the machine, which is oblong and rectangular in form and comprises in its construction two longitudinal side sills 2, two upper longitudinal supporting-bars 3, mounted on posts .12, rising from said sills, and upper and lower cross-pieces 5 and 6, respectively connecting the sills and supporting-bars. This particular construction of frame, while deemed preferable, is not essential and may be altered to suit varying conditions, and, if desired, said frame may also be mounted on wheels, so as to permit of the machine being transported from place to place to work in a field or alongside a thresher.

The baling or compression chamber 7 extends from the center of the frame to the rear or delivery end thereof and is open at both ends and formed by a bottom 8, sides 9, and a top 10, said sides being provided at the mouth of the chamber with longitudinal slots or openings 11 for passage of the needles, by which the binding-wires are threaded across said chamber in the manner hereinafter described. Mounted upon the supporting-bars 3 at the front or opposite end of the frame is a feed chamber or hopper 2, open at its rear end and provided with a curved bottom 8, which preferably forms, as shown, an extension of the bottom of the compression-chamher. The hopper is divided centrally to form a feed-chamber proper, 13, at its front end and an open compartment M in rear thereof by spaced gl'lide-strips 15, which are curved and extended rearwardly at their lower ends and connected to the top of the baling-chamher or to the intermediate cross-piece 6 above the mouth thereof.

Mounted transversely at the rear or open end of the compartment 11 is a power-shaft 16, having a central crank arm or portion 17 and carrying at one end a belt-wheel 18, adapted to receive power from a threshingmachine or suitable motor, and at each end a bevel-pinion 19 19. A feeding-fork 20 is provided with a head 21, loosely mounted on the crank portion of the power-shaft, a series of prongs or tines 22, which project through the guides 15, and an arm 23, which works loosely in an opening in an oscillatory bearing-block 21, mounted in rear of the hopper and by which the fork is guided in its travel. In operation as thepower-shaft revolves in the direction of the arrow, Fig. 3, the fork turns therewith, and the tines thereof travel in the are of a circle through the hopper and carry the hay or straw to the mouth of the baling-chamber, and then the fork moves upward in a direct vertical line to withdraw the tines from engagement with the straw. During this operation the arm'of the fork moves freely through the oscillatory block, and the latter turns on its axis to compensate for and to enable the fork to traverse its irregular path with ease and without binding.

Arranged above the baling-chamber and on opposite sides thereof are parallel shafts gears 27, which mesh with the bevel-pinions' 19 and 19 on the power-shaft. These shafts also carry at their outer ends bevel gearwheels 28, which mesh with like gear-wheels 29 on the upper ends of vertical crank-shafts 30, journaled in side extensions of the frame and located on opposite sides of the balingchamber at the delivery end thereof. Said shafts operate the packers which force the straw fed by the feed-fork into the balingchamber and compress the same therein. Each packing device consists of a longitudinal carrier 31, mounted to reciprocate in guides on the side of the baling-chamber, which carrier is provided with upper and lower flanges 31 to receive the inner ends of a right-angularly-reciprocating arm 32 and connecting-rod 33, which are pivoted thereto near their inner ends and jointed at said ends to each other. The outer or free end of the arm carries a packin g-fin ger 34:,that is adapted to move through a guide-opening in the inner end of the carrier and projects through one of the openings 11 into the mouth of the balingehamber, while the outer end of the connecting-rod is journaled upon the crank portion of the shaft 30. \Vhen this shaft turns, the carrier is reciprocated hack and forth longitudinally of the baling-chamber, and at the same time the packing-finger 3% is reciprocated transversely, so as to move into and out of the mouth of said chamber. This operation will be readily understood byreference to Figs. 6, (3, and 9 of the drawings, from which it will be seen that when the arm 32 and rods 33 are in longitudinal alinement, which position they assume when the crank portion of the shaft moves closest to the baling-ehamber in making one half of a revolution, the packing-finger projects to its fullest extent within the mouth of the baling-chamber and the carrier is being reciproeated toward the delivery end of said chamber, and that, on the contrary, when the crank portion of said shaft moves outwardly from the baling-ehamber in making the other half of its revolution the carrier is reeiprocated in the reverse direction, or toward the mouth of the baling-chamber, and the free end of the connecting-rod drawn out wardly, whereby the inner end of the arm is forced inwardly toward the chamber and the outer end thereof away from the chamber to withdraw the packingfinger, as indicated by broken lines in Fig. 0. The operation of the packers is so timed with respect to that of the feeding-fork that when the fork moves through the hopper to force the straw toward the baling-chamber the carrier moves inwardly and the beating-finger outwardly, as shown by broken lines in Figs. (Wand 9, thus allowing the fork to move freely into the month of said chamber. the fork begins to move upwardly, as before Vhen, however,

described, the carrier is reeiprocated in the reverse direction and the beating-finger proected into the mouth of the baling-chamber,

ant 25*, carrying at their inner ends beveli so that as the next feeding movement of the fork commences the fingers will force the hay or straw previously fed into the chamber, and this operation is continued until a s ufficient amount of straw is compacted therein to form a bale, whereupon the tie-wire threading, twisting, and cutting mechanism is automatically thrown into operation, as hereinafter described. For the purpose of preventing rebounding of the straw. a pair of spring-actuated dogs or hooks 35 are provided on each side of the mouthof the baling-chamber. These hooks are adapted to be forced back out of the way to allow the straw to enter the chamber and then springback into their normal positions to retain the straw therein.

Located at one side of the machine is a wirethreader consisting of a frame 36, formed of a pair of arms or bars 37, arranged one above the other and pivoted at their inner ends to the frame near the crank-shaft 30 to swing in a direction transversely to the baling-chamher, said arms being provided with longitudinal slots 38, in which the cranked portions of a double-crank shaft 39 are fitted to slide. The outer ends of these arms are connected by a head 40, carrying a pair of inwardlyprojecting needles 41, provided at their free ends with eyes 42 for passage of the bindingwires, which feed through guides 42 from reels (not shown) mounted alongside the machine. These needles are adapted to move through the openings 11 to thread the tiewires across the mouth of the baling-chamber both before and after the formation of a bale, and simple and effective automatic mechanism is provided for positively effecting this operation. Mounted upon the upper end of the shaft 39 is a bevel-pinion 43, which is adapted to mesh with aro-tatingsegment 44, carried by an arbor 45, loosely mounted on the side shaft 25 and provided with a clutch-head 46. This segmentis of peculiar construction, being provided with peripheral spur-teeth 44,which are extended on one side thereof to form bevel-teeth 44 Pivoted to said segment is a pawl 47, having a lug or tongue 48, adapted to engage a notch 49 in said clutch-head to rigidly connect the segment thereto, so that it will turn with the shaft. The pawl is normally held in engagement by a ribbon-spring 50. A toothed tripwheel 51 is rigidly mounted on a revoluble shaft 52 above the baling-chamber, and the lower peripheral portion thereof normally projects thereinto through a slot in the top 10 of said chamber. This shaft 52 carries a striker 53,which when the wheel is revolved is adapted to depress the looped arm 54 on one end of a short transverse rock-shaft 55, which shaftis provided at its other end with an arm 56, normally held 'in engagement with the pawl 47 by a spring 57 acting on said looped arm to' keep the lug or tongue 48 of said pawl from engaging with the cl utch-head 46. Normally that is, when the baling-chamber is being filled-the rotating segment, crank-shaft 39, and the wire-threader frame remain at rest,

the clutch-head 4G alone turning with the shaft; but when the chamber is nearly filled the straw forced thereinto by the packers comes in contact with the toothed wheel and causes the same and its shaft to turn. hen the striker 53 depresses the looped arm 56 of the rock-shaftv 55, the latter, through an action of spring 50, 'is operated to withdraw its arm from engagement with the pawl 47, whereupon the latter engages and rigidly connects the rotating segment with the clutchhead turning with shaft 25. As the segment revolves, the beveled tooth portion 44 thereof meshes with the pinion 43, and the crankshaft 39 is thereby operated to m ove the wirethreading needles across the mouth of the baling-chamber' and then back again. When the segment completes its revolution, it again com-es into contact with the arm 56 and is re leased from engagement with the clutch by said arm at the same time that the needle is fully reciprocated.

The peculiar manner in which the wire is threaded and clamped will be described more fully hereinafter in connection with the wire twisting and cutting mechanism.

Above the mouth of the baling-chamber is mounted a transverse shaft 58, carrying at its innerend a bevel-pinion 59 and at its outer end a cam 60, having a peripheral groove. The said pinion 59 meshes with a similar pinion 61 on one end of a short counter-shaft 62, extending parallel with the shaft 29, and said counter-shaft carries at its opposite end a spur-pinion 63, which is adapted to mesh with the spur-teeth 44 on the rotating segment 44, whereby all three shafts 39, 58, and 62 will be operated in quick succession by the segment Arranged on the opposite side of the frame from the wire-threader is a clamping device consisting of a pivoted bell-crank lever 64, arranged below the cam and having a. curved upper vertical arm 65, projecting into the groove of said cam, whereby it is positively connected therewith, a lower vertical arm or extension 66, and a horizontal arm 67, adapted to bear upon the upper side of a division-bar 08, extending between the two intermediate posts 4 on one side of the mouth of the balingchamber. Pivoted to said bar is a gravity-clamp 69, having a long arm 70, adapted to bear against the under side thereof, and a short arm 71, adapted to be depressed by the said lower arm or extension (30 of the bell-crank lever. These clampingarms are adapted to be operated simultaneously with the wire-threader frame, and as the needles of saidframe thread the upper and lowerbinding-wires across the frame the peripheral face 60 of said cam, which is of the greatest distance from the shaft 58, tilts the lever 64, and the arms 67 and 70 are thereby operated to clamp the wires in the manner hereinafter described. As before stated, the needles are operated both prelimin arily and subsequently to the packing of the hay or straw in the compression chamber,

and the wires in addition to being engaged by the clamps are threaded into the jaws of the cutting and twisting mechanism yet to be described. The wires 72 when stretched preliminarily across the mouth of the balingchamber are forced backwardly thereinto,and the mass of hay or straw compressed by the packers impinges against'said wires, which are thereby drawn outwardly toward the discharge end of said chamber in the form of a loop 73 and caused to embrace the sides and rear end of the bale being formed, the wires freely unwinding from the reels and passing through the eyes of the needles at one side of the machine and the free ends thereof being firmly held by the clamps 67 and 69 at the other side. It will thus be seen that the wires are bound tightly around both sides and the rear end of the straw and assist in its compression, and when the required amount of straw is compressed to form a bale the needles must again be operated to extend the wires across the inner end of the bale and thread new strands across the mouth of the balingchamber for the reception of the straw compressed to form the succeeding bale.. The mechanism for carrying this operation into practical effect has been hereinbefore described, and we will now proceed to describe the mechanism whereby the wires are automatically clamped, twisted, and cut.

Arranged on the same side of the frame as the clamp 64 in transverse alinement with the mouth of the baling-chamber and on the opposite side of the frame from the wire-threading device is a frame H, composed of the graduated. standards or pillows 7%, 74 and 74 the two latter having upper and lower crossbars 74 and 74, respectively. In an arm or bearing projection rising from the intermediate standard 7t is journaled the extended end 58 of the shaft 58, and mounted thereon is a spur-gear 7 5, which is arranged above and communicates motion through the medium of a pinion 75 to a gear-wheel 75, which in turn meshes with a gear-wheel 75 similar in all respects in construction thereto. These gears 75 and 75 operate the upper and lower sets of devices, which cut and twist the free ends of the upper and lower binding-wires, and as said devices are duplicates a description of one will suflice for both. These devices, it may be stated for the sake of brevity, are respectively mounted in the upper and lower cross-bars or standards 74 and 74: of the frame. The gear-wheel 75 then is provided in its inner side with two concentric camgrooves 76 and 77 of circular form except at one point, where their walls are deflected to form projections 76 and 77, respectively, said projections being in line with each other and the groove 76 being widest adjacent to its projection. Mounted upon the cross-bar 74 of the front or inner standard 7 .9 of the frame is a clamping-jaw 78, adapted to move horizontally toward and from a fixed jaw 79, also mounted upon said cross-bar and provided with a rearwardly-projecting arm 80, carrying a friction-roller 81, which traverses the said cam-groove 7 (5 in the gear 7 5 Arranged immediately below said jaws is a twister 3,11%, cutter comprising a shaft or spindle 82, re atably mounted in the said cross-bar 7M and carrying at its front end a cutting-jaw 83, grooved on its inner face and provided at its rear edge with a cutting-blade S4 and at its rear end a pinion R l, which meshes with the gear 7 5 To this spindle is pivotallyconnected a complemental spindle 85, carrying at its inner enda jaw 86, ribbed on its inner face to tightly clamp the wires in the groove of the jaw 83 and normally held out of contact with said latter jaw by an interposed tension-spring S7. The twisting and cutting jaws are arranged in advance of the clamping-jaws and are somewhat longer than the same, so that the upper ends of the jaws of both sets have position in the same plane, and the upper ends of the jaws 79 and 83 are beveled off and made somewhat shorter than the jaws 78 and 86, so as to facilitate the feed of the binding-wires thereto. At its inner end said spindle 85 carries a frictionroller 88, which is adapted to traverse the wall of a groove 89, formed in the crossbar 7% of the intermediate standard 74 of the frame. Opening through the wall of the groove at one point in the circumference thereof is a horizontal slot 90, in which a bearing-block'9l is arranged to slide, said block being normally pressed toward the groove 89 bya spring 92 and provided with a segmentshaped outer face 93, which when the block is in its normal position completes the circular formation of the wall of said groove 89. To the bearing-block is connected a reciprocating retractor 94, which carries a pin or roller 95, projecting into the groove 77 of the gear-wheel 75".

From the above description of the construction and arrangement of the parts it will be apparent that as the gear-wheel 75 revolves in the direction of the arrow, Fig. 12, the pivoted jaws of the clamp and twister, which normally stand open in vertical position, will be closed against the fixed jaws by reason of the roller 81 traversing the narrow portion of the slot 76 and the roller 88 the walls of the groove 89, thus connecting said jaws and their spindles 82 and 85, so that they will rotate in unison. \Vhen the roller 81 on the jaw 78 and the pin 95 on the retractor 94, however, reach the projections at the defiected portions of grooves 76 and 77 in gear 75 the jaw 78 will be forced open by the projection 7 6 and the retractor 94 moved outwardly by the projection engaging its pin 95, whereupon the bearing-block 91 will be retracted against the tension of its spring 92, and the spring 87 will force the jaw 86 open, and the roller on the spindle 85 thereof will occupy the open end of the slot vacated by said block, as shown in Figs. 12 and 16. The jaws will then stand open -tated to twist and cut the wires.

ready to receive the. wires, and when said jaws are again operated in the manner above described the clamping-jaws 7S and 79 will engage the wire in rear of the twisting-jaws 83 and 86 and hold the same while the threading-needles are retracted to stretch the wires for the succeeding bale, and simultaneously therewith the latter jaws will be rapidly ro- The corresponding sets of devices which cut and twist the ends of the lower binding-wires are, as before stated, similarly constructed, but mounted upon the cross-bars 7 4 of the standards 7 4 and 74. Each gear-wheel 75 and 7 5 is provided in its outer side with a recess or depression 96, which is engaged by a springpressed detentroller 97 on the frame to quickly arrest the motion of said wheels when the jaws are opened by the projections of the cam-grooves therein. By this means the parts are always maintained in their normal operative positions and all liability of the jaws being closed on account of the gearwheels turning beyond the proper point by momentum obviated.

The construction and mode of operation of the several coacting elements of the machine having been described, the manner in which the binding-wires are threaded and tied will now be briefly set forth. Preliminarily the ends of the wires 7 2 are threaded through the eyes 42 in the needle 41 and bent back to form trailing portions 98, which are somewhat shorter than the distance between the clainping-jaws 78 79 and cutting and twisting jaws 83 86. Then the threader is moved across the mouth of thebaling-chan1ber, the trailing portion of each wire is carried past the twisting-jaws, but deposited in the clamping-jaws, as shown in Fig. 17, which close and clamp it. The needle is then retracted and the wire stretched thereby across the mouth of the baling-chamber is forced back by the straw into'said chamber in the form of a loop 73, which embraces the' sides and outer end of the bale, the wire unwinding from the reel and passing freely through the eye of the needle. During this operation the clampingjaws 78 79 again open and the intermediate portion of the wire is drawn back between the cutting and twisting jaws 83 86 and under the upturned end of one of the clampingarmsthe arm (37, for instance-which opposes a frictional resistance to the release of the trailing-portion 98. After sufficient straw has been compressed to form a bale the nee-' dle is again operated to stretch the wire across the inner end of the bale and complete the formation of the binding-loop, the end 100 being deposited between both sets of jaws 78 79 and 83 86 and clamped by the clampingiron 67. The jaws then close about the portions 99 100 of the wires and firmly clamp them while the needle is being retracted, and the jaws 83 86 are rotated to twist and out said portions of the wires, as shown in Fig.

20, the several ends of the feed-wire being held by the jaws 78 79, while the needle is moving back to stretch the wire across the mouth of the baling-chamber for the succeeding bale. This operation is illustrated in full in Fig. 21. While the above explanation in the main applies to a single binding-wire the upper one-it will of course be understood that the operation of threading the lower wire is the same, said lower wire being, however, engaged by the lower sets of clamping and twisting jaws and lower clamping-arm 7 0.-

It will be obvious that the construction and arrangement of the parts of the machine may be varied to a considerable extent without departing from the spirit or sacrificing any of the advantages of the invention.
